SUMMARY OF THE INVENTION

During rainy, foggy or other inclement weather, whenever the windshield wipers of a motor vehicle are operated, it is often, if not usually, advisable to simultaneously activate the headlights (and, perhaps, other vehicle lights), in order to provide greater visibility to other motorists. However, motorists often fail or forget to activate their headlights at such times, particularly during daylight hours.

Additionally, some states may require that the headlights of a motor vehicle be activated whenever the weather conditions are severe enough to require use of the windshield wipers.

Moreover, motorists are often forgetful of turning on their headlights at dusk, and turning them off at dawn or when exiting from an artificially darkened situation, such as the emergence from a tunnel, etc.

Accordingly, one object of the present invention is the provision of an apparatus for automatically illuminating the headlights (and, optionally, other lights, such as parking lights, etc.) of a motor vehicle, whenever the windshield wipers of the motor vehicle are turned on.

Another object of the invention is the provision of such an apparatus which will simultaneously, in conjunction with the above-described function of automatically illuminating the headlights upon activation of the wipers, automatically illuminate the headlights of the vehicle whenever the ambient light falls below a threshold value and deactivate the headlights whenever the ambient light exceeds a threshold value.

The invention will now be described by way of a particularly preferred embodiment, reference being made to the accompanying drawings, wherein:

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic diagram of the ignition switch, light circuit, and wiper circuit of a motor vehicle equipped with an apparatus for automatically illuminating the headlights, parking lights, etc. of the vehicle according to the present invention; and

FIG. 2 is a schematic diagram of a photosensitive circuit and an accompanying solenoid used in the apparatus of FIG. 1.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows, in schematic block diagram form, a lighting control apparatus constructed according to the present invention for automatically illuminating the lights (e.g., headlights, parking lights, etc.) of a motor vehicle. The motor vehicle includes an ignition switch 10, headlights 12, parking lights 14, a light control switch 16 of a type well known in the art that can illuminate either the headlights 12, the parking lights 14, or both, and a wiper device 18, for example, windshield wipers and/or a rear window wiper, the wiper device 18 itself including a wiper motor 20 and a wiper control switch 22 for actuating the wiper motor 20. The wiper device 18 may also include a variable speed wiper actuation device consisting of a low speed wiper switch 24, a high speed wiper switch 26, and a wiper delay switch 28, which permit the wiper motor 20 to be selectively actuated at either a low speed, a high speed, or at delayed intervals, as is well understood in the art.

The motor vehicle additionally includes an electrical power supply, most commonly a twelve volt D.C. automotive battery 30, one terminal of which (normally the positive terminal) is connected to the lights, that is, the headlights 12 and the parking lights 14, through the light control switch 16, and to the wiper motor 20 through the wiper control switch 22 (and optionally through the low speed switch 24, the high speed switch 26, and the wiper delay switch 28, if present). In the embodiment shown in FIG. 1, the 12 volt D.C. battery 30 is illustrated as supplying voltage and current directly to only the ignition switch 10 and the wiper control switch 22, with the light control switch 16 receiving its power indirectly through the ignition switch 10 via a connection 32. However, it will be understood by those of ordinary skill in the art that a 12 volt battery connection can be readily made directly to the light control switch 16.

According to the invention, a photosensitive circuit 34 is positioned on the motor vehicle in such a location that it will be struck and illuminated by the general ambient light conditions to which the motor vehicle is exposed. The photosensitive circuit 34 is electrically connected in series between the 12 volt supply from the battery 30 and the lights, preferably both the headlights 12 and the parking lights 14. Thus, the photosensitive circuit 34 forms an electrical circuit that is in parallel to the light control switch 16, whereby the headlights 12 and the parking lights 14 can be illuminated (that is, turned on) via either the light control switch 16 or the photosensitive circuit 34. It is to be understood that, rather than being connected to the 12 volt supply of the battery 30 indirectly through the ignition switch 10, the photosensitive circuit 34 could instead be connected to the 12 volt supply of the battery 30 directly.

Additionally, according to the invention, a control connection 36 is provided between the wiper control switch 22 and the photosensitive circuit 34, the control connection 36 being energized with the 12 volt supply of the battery 30 whenever the wiper control switch 22 actuates the wiper motor 20, whether through the low speed switch 24, the high speed switch 26, or the wiper delay switch 28.

The photosensitive circuit 34, which is shown in more detail in FIG. 2, includes a photosensitive element 38 that has a first state wherein the photosensitive element 38 is substantially conductive when the intensity of light falling thereon is below a first threshold value, and a second state wherein the photosensitive element 38 is substantially nonconductive whenever the intensity of light falling thereon exceeds a second threshold value. Such photosensitive elements are well known in the art and are described, for example, in U.S. Pat. No. 4,968,895 issued on Nov. 6, 1990 to Leclercq and entitled "Laminated Glass with Photosensitive Element and Automatic Device for Turning On and Off Lights of a Motor Vehicle," this issued U.S. Patent hereby being expressly incorporated by reference, with the same effect as if the entire contents thereof were fully set forth herein.

The photosensitive circuit 34 additionally includes a shutter member 40 slidingly mounted between a pair of parallel tracks 42, such that the shutter member 40 can be disposed in either a first position to substantially shield the photosensitive element 38 from the ambient light, or a second position to substantially expose the photosensitive element 38 to the ambient light. The shutter member 40 is connected to a piston rod 44 of a solenoid 46 which acts to move the shutter member 40 laterally between the first and second positions, the solenoid 46 being actuated to move the shutter member 40 into the first position, wherein the photosensitive element 38 is substantially shielded from the ambient light, whenever the solenoid 46 is energized by the control connection 36 extending between the wiper control switch 22 and the solenoid 46. Additionally, the photosensitive circuit 34 is provided with an input 48 from the 12 volt supply of the battery 30 (preferably via the ignition switch 10) and an output 50 to the lights of the motor vehicle (e.g., the headlights 12, the parking lights 14, etc.).

In operation, the light control apparatus functions as follows: Whenever the wiper device 18 is actuated via the wiper control switch 22, a control signal (for example, a 12 volt current from the battery 30) is transmitted to the solenoid 46 over the control connection 36, thereby energizing the solenoid 46 and causing the shutter member 40 to move to the left in FIG. 2, thereby substantially reducing the ambient light falling on the photosensitive element 38, which becomes conductive and electrically connects the lights of the motor vehicle (e.g., the headlights 12, the parking lights 14, etc.) to the 12 volt supply of the battery 30, thereby illuminating the vehicle lights. The vehicle lights are thus automatically illuminated whenever the wiper device 18 is actuated, regardless of the ambient lighting conditions. Additionally, during those times when the wiper device 18 is inactive, the photosensitive circuit 34 functions to automatically illuminate the vehicle lights whenever the ambient light falls below the first threshold level (e.g., at dusk), and to turn off the vehicle lights whenever the ambient light exceeds the second threshold level (e.g., at dawn). Still further, the vehicle lights can be conventionally illuminated via the light control switch 16 at all times.

While the invention has been herein described by way of a particular preferred embodiment, various substitutions of equivalents may be effected without departing from the spirit and scope of the invention as set forth in the following claims.
